Association of translation factor eEF1A with defective ribosomal products generates a signal for aggresome formation.

Abstract excerpt

Aggresome formation is initiated upon proteasome failure, and facilitates autophagic clearance of protein aggregates to protect cells from proteotoxicity. Here we demonstrate that proteasome inhibition generates a signaling event to trigger aggresome formation. In aggresome signaling, the cell senses a build-up of aberrant newly synthesized proteins. The translation elongation factor eEF1A associated with these...
